What I'm trying to do
is make a grid of invisible coordinates on the page equally spaced. I then want a <div> to be placed at whatever grid coordinate
is closest to the pointer when onclick
is triggered. Here's the rough idea:
I have the tracking of the mouse coordinates and the placing of the <div> worked out fine. What I'm stuck with
is how to approach the problem of the grid of coordinates.
First of all, should I have all my coordinates in an array which I then compare my onclick coordinate to?
Or seeing as my grid coordinates follow a rule, could I do something like finding out which coordinate that
is a multiple of whatever my spacing
is is closest to the onclick coordinate?
And then, where do I start with working out which grid point coordinate
is closest? What's the best way of going about it?
Thanks!
